Introduction to the Stackdriver Monitoring API

The Stackdriver Monitoring API v3 gives you access to over
900 Monitoring metrics from Google Cloud
Platform and Amazon Web Services. You can create your own custom metrics and
can organize your cloud resources using groups.

Alerting policies

Beta

This is a Beta release of
the AlertPolicy endpoint in the Stackdriver Monitoring API. This feature
is not covered by any SLA or deprecation policy and might be subject to backward-incompatible
changes.

An alerting policy is a configuration resource that describes the
criteria for generating incidents and how to notify you when those incidents
are created. Alerting concepts explains the basic concepts
of alerting policies. For more information, see the
AlertPolicy reference.

The API also lets you create alerting policies based on a ratio of two metrics.
Ratios cannot currently be created through the Monitoring console.
For more information, see MetricThreshold in the
AlertPolicy reference.

Notification channels

Beta

This is a Beta release of
the NotificationChannel endpoint in the Stackdriver Monitoring API. This feature
is not covered by any SLA or deprecation policy and might be subject to backward-incompatible
changes.

A notification channel is a configuration resource that describes how
to notify you when incidents occur. Notification channels can reference a
variety of different kinds of communication services and endpoints; these
are specified in descriptors. The descriptors determine the
set of configuration parameters that are included in a channel object.
